. noon CONSTRUCTION.

To all whom it may concern:

Be it known that I, CHARLEY BURNETT, a citizen of the United States,residing at WVashington Court House, in the county of Fayette and Stateof Ohio, have invented certain new and useful Improvements in RoofConstruction, of which the following is a specification.

This invention relates to roof construction and aims particularly toprovide the.

type of structure which may be both very readily applied v and whichwill be proof against rattling or ready dislodgment by the action of thewind when the latter reaches considerable velocity.

Still a further object of the invention resides in so forming andarranging the structure that the metal roofrsections, when used inconnection with inclined rafters and a ridge pole, may be suitably slidandoverlapped and secured tothe ridge pole and in this manner eliminatethe possibility of wind and air from entering the interior of thestructure.

Another object'of the invention resides in a structure whereby theoverlapping edges of the roof sections'are secured in'position toprevent the admittance of moisture ,to a position beneath the metalsections and to also prevent corrosion of the attaching nails.

The preferred embodiment of this invention is shown in the accompanyingsheet of drawings, in which similar characters of corresponding parts,and in which: n

Figure 1 is a partial side elevation and partial section of a roofsection constructed in accordance with my invention,

Figure 2 is a transverse vertical section of the structure shown inFigure 1 taken on line 2-2 of Figure 1. 1

Figure 3 is an enlarged vertical section taken through one of therafters, showing the manner of connecting the roof sections thereto,and, V

sections are preferably concaved, as is shown, and have theirlongitudinal edges bent to conform in shape to the rafters themselves.Along the edges of these sec tions, there are provided a plurality ofaper- Patented Feb; 7, 1922.; Application filed February 12, 1917.Serial No. 148,033. R I

tures or punchings so formed that a burr 5 v 1 is formed which projectsupwardly, as is shown particularly in Fig. 3. Through these aperturesthe attaching nails 6 are made to pass, but in order to form a tightjoint and to prevent the admission of moisture be- 5 neath the roofsurface each nail is provided with'a washer 7,whioh washer is'preferablyof lead. I As the nail is driven down, this washer embeds itself in theburr formed and in turn wedges it tightly against the nail or the washeritself is embedded in this burr'so that a very tight joint is formed. I

In order to-form a tight joint along the ridge pole, the end which abutsthis ridge pole is slitted, as shown at 8, the depth of this slit' beingthe amount it is necessary to bend up the flaps 9 thus formed due'to theconcavity of the metal plate sections. Thus, by comparing Figures 1 and2, it will be noted that the plate'sections are slitted a distancesufficiently to cause a tight joint to be'formed between each of theflaps f9 thus'formed, the line ofcontact'varying'in length from theedges toward the'center; In

thus bending the flaips up, the slitted: ends also overlap and it isthrough this over lapped portion that the sections maybe, fit-T tachedto the ridgepole, as is showman-10;"

This prevents the flap sections from pulling apart, although, ifdesired, additional nails may be placed through the flap "portions.

Finally, a ridge roll of the type shown at 11' is placed in position togive afinished appearance. j

From the foregoing description, it will be apparent that I have provideda type of structure wherein a very rigid roof is made and one whereinalso all jointed connections are made water tight.

The ridge roll itself is preferably formed from sheet metal, and is soshaped as to adapt itself to the configuration of a ridge pole and theco-operating upper portions of the roof sections. In this instance, saidridge roll comprises a substantially fiat upper portion 12, which isadapted to be positioned upon the corresponding upper surface of theridge ipole 1, fastening elements 13 being employed to secure the samein a rigid position; The portion 12 terminates in obliquely anddownwardly directed sides 14, which extend substantially parallel withthe roof sections 4. The lower edges of the sides 14 terminate in rightangularly disposed supplemental sides 15, which are situated at rightangles to said roof sections,

the lower edges of the supplemental sides being formed so as to fiushlyengage with the undulating cross sectional vformation of the roofsections. By virtue of this ridge roll construction and the co-operationwhich exists between the same and the roof sections, a structure isprovided which is conformed to include a fiat upper portion ar-' rangedto directly contact with the upper J portion :of 'said pole, fasteningdevices ar-v ranged to pass through the fiat upper portion of said ridgeroll and to directly connect the latter with -said pole, said roll beingfurther formed to include sides disposed parallel with-said sections andin spaced relationship therefrom, and integral supplemental sidesdisposed. at} right angles to the first mentioned sides, ssaidsupplemental sides having their lower-edges undercut to evenly engagewith the undulating curva- V ture'of said sections. 7 7

2. In a roof structure, the combination with a ridge pole,"of aplurality of concave metallic roof sections, cooperatively "supd' inconnection, with said pole and sloping downwardly therefrom, a ridgeroll formed to include a substantially flat upper portion, reverselyinclined sides extending downwardly from the flat upper portion of said.roll and in parallelism with said roof sections, supplemental sidesdisposed at the lower edges of said firstnamed sides and in angularrelation with respect thereto, the

said supplemental sides having the lower edges thereof formed to evenlyengage with the concave surfaces of said sections, the said sidesserving to cover the connections between the said roof sections and saidpole, and fastening devices arranged to pass through the flat upperportion of said roll, and to connect the latter with the upper portionof said pole. 7

3. In a roof structure, the combination with a ridge pole, of aplurality of transversely concave metallic roof sections having theupper edges thereof secured to the opposite. sides of said pole, ametallic ridge roll disposed upon the upper surface of said pole andarranged to cover the] meeting joints defined by the connection betweensaid sections and said pole, the said ridge roll being formed to includereversely and down-j wardly inclined sides extended away from said poleand in substantially parallel rela- V t-ionship with said roof sections,ysupplemental sides disposed .at the lower edges" of said first namedsides and in angular relation with respect thereto, thesupplementalsides having their lower edges formed .to conform with the transverseconfiguration of saidsections, and fastening devices situate'd betweensaid-sides forconnecting the roll to the upper part'of said pole. I

In testimony whereof I affix mysignature in presence of two witnesses.
